and each vextendinga substantially equal distance beyond each end of the bale 1, whereby the end portions maybe folded inward to be or Voverlap. each other and entirely cover 'each end of the bale. Y

that .the wrappershown. and. describedcherein, may be applied to the bale by forming onewrapper of=l greater length. thanl they other, as shown in my .pending application Serial Number 284,042, filed :June r8, 1928, or thewrappers may be formed' of equal length andso applied to the bale or packagethat one endlof each wrapper extends to orslightly'overlaps one end ofthe balewhile the opposite end of Vsueh wrapper extendsA a. sulficient distance vbeyond the end of the bale to folded over and serve as-.aprotection for theentirebaleencl i' vAs shown herewith, each wrapper 2 and 3 is formedfrom ajcentral pleated section 4 and plain unpleated end sections 5 and 6, each' end sectionV being. securedto the section 4 by a line ofstitches 7 orfother suitable means.

-Thepleated wrappersections 4 may be formedi-n several ways, such, for example, as

illustrated i11.Figs. 2,3 and V4 ofthe' drawings.

In the form lof wrapper illustratedin Fig. 2 o f 4the `drawings,. 'th`e laminated wrapper 8 is formed from a heetfof paper Qiandjasheet Y or layer off fa.bric -materialflO'secured together substantially throughout their extent, as by means ofa suitable adhesive material to form a substantially unitary :laminated sheet. The sheet 8 is then foldedto form therein a plurality of pleats or folds i 11 which are arranged substantially 'parallel with each other. Y l

The fabric-material employed in forming the various laminated sheets illustrated herein is preferably made from some inexpensive fibre, such as, for example, jute, sisal, cotton waste, burlap fibre, and the like, and the fabric material may be formed by weaving the iibresto forma loosely woven sheet material, or ythe fabriematerial may be. formed by laying uniformly spaced strands or threads of the fibre uponV the paper sheet 9 l towhich: an adhesive substance has beenapplied, flh'e woven or unwoven fabric material'is secured-tothe-paper sheet or sheets with whichit istobe. united by the adhesive mate- 'rial' and the laminatedv sheet thus formedis dried and, if. desired,the laminated sheet may bepassed between suitable pressure rolls or otherwise treated to pressthe paper sheet and fabric'layerl in to close relationship with each other in formingthe laminated sheet material.

n The 'laminated sheet 8, vas shown 4Fig.

2,. is providedwith afplurality of folds 11 formed therein and. isvtobe employed for.

forming thecentral'seetion 4 ofthe lwrapper as shown in Fig. ,1,1 wherein the'laminated sheet 8V provided with folds 11 overlies the balewith the ends thereof Yextending slightly beyond the ends of thebale asf at 12.

The form of composite sheet Vmaterial hown'in Fig.. 3 of the drawings is adapted foriise, asis the materialshown in Figl 2,

Vof the drawings, Vfor forming the centralsections4 ofthe completed wrappers, and comprises Aa` layen orsheet previously described andshown in Fig, 2, a

sheet'of unpleatedlpaper 14, and a paper sheet plurality A of lvwhich is provided withv a pleats orfolds *16, the pleats or folds lin the i sheetl being arranged substantially paralform'ed in the laminated sheet 8. The several sheets 8, 1 4 and`1'5 may be joined together at intervals by stitches o'r staples (not two paper sheets 19, thefabric material being united to the paper sheets by ya Asuitable adhesive' material, and the entire sheetr being folded to form therein a plurality of pleats 20. The centralv wrapper sections 4 may be formed from thesheet material as shown in Figs. 2, V3) and '4 ofthe drawings, or from other arrangements of sheet material, j such as, for eXa1nple,-the combination of the vsheet material 8 with one or more pleatedpaper sheetswith Vor without the inclusion of anun- (los lel with each other and with the pleats 11 lie against separation from each other in hanf pleated. sheet as shown in Fig. 3, orby corn- I sheets by means of bining the` form` of sheet materialshown. in Fig. 4 and designated generally lby numeral 17, 4with one or more pleatedpaper sheets after almanner'similar to that illustrated in Fig. Seither with orwithoutthe unpleated paper sheet-14.` f

'Y In the formation `of the laminated sheet materialillustrated invFigs.` 2Yrand 4, I may unite the fabric layer to one ory more paper ria'L-as by coating.the-papersheets with hesive, applying the fabric layer theretoand passing the :composite sheet through rollsl to press the fabric and paper material into vintimate contact. After thel fabric; layer: and

v paper sheet have been united together as A plurality Y shown in Figs.

arranged subfrom the eXpansibe material when undergoing 2 Y compression to formstandard or high density f bales after the initial compression f andlthe application of the wrappers. Similarfopem ings Y( not shown) may be formed in the wrap# pers shown in Figs. 2 orV inlsuch other modified formsas maybe used for Vthe central sections of the wrappers in orderto permit lescape of theair from the eXpansible material when the bales are` given @Second compression. I'

Iii-Fig.` 5 vof the drawingsfthere is shown a` laminated sheet 13 9 and a layer of fabric material lO which is similar `in all respects tothe sheet, SeXceptV Y that the laminated sheet is knot folded to 'form pleats 1l therein after the fabricflayer andpaper-sheet have been uniteditog'ether. The sheet material Al3'is utilized for-ferming` :the end sections 5 and 6 of the wrapper, which arejoine'd to the central sections 4 by stitches Vas previously described, for Vforming the completed wrappers 2 and y `In the packaging of raw cotton the cotton is first given an initial compression, thewrap-Y pers previously placed in the pressare then folded to conform tothe bale and bale ties placedrtherearound to form what are known' as gin bales.` These gin bales maybe and fre# quently are given a second compression, without removing thewrapper, to form what areY or high density bales. In Y the case of these highly compressed bales on 7 known as standard bales which are `to `be subjected to much hanV` dlingorjrough usage ,a composite' fabric'and i paper 'wrapper Y preserves the Vmaterial fromy injury or waste and rtends r,to prevent tearing of the wrapper by hooks in handling. j It'will bel seen also that a suitable adhesive mate-.-

wrappers. 27 are applied to thefbale 36 as shown in Fig. 8, and after initially compressed-,the parts ofthe wrapper are so proportioned that the paper ends ofthe end sections 29 and 30 will meet or overlie slightly to permit the paper ends to be Afolded over each other at 37, while .the ends of the fabric sectionsk 32 will fail to meet across the end of the' bale but will ter-V niinate.v at 38, v Y

.After the secondcompression of thebale, the bale twill be reduced sufficiently so. that the free ends 38 of the fabric will; meet andfpermittheir being securedtogetherfby stitching or in any other suitable manner if desired'. lt will be seen that by making vthe paper portions of the end'sections of greater` length than the fabric portions, thoseparts of-theend sections composed of paper Y suiiciently' to cover theends of the bale after the first compression to which the material is subjected, while after the second compresl sion the thickness of thel bale will be so reduced that the yfabric will cover the entire end of the bale, andthe absence Vof'anexcess'. of fabiic at the balefend: will prevent the for-Y mation of an ungainly niassof fabric which would otherwise be-formed attlie-end of the bale after'the second compression, as wellas resulting in aconsiderable saving of mate-Y rial. i
